Recreational sedatives are aces in the hole for those prone to anxiety, nervous flyers or Jennifer Lawrence when she's about to film a Hunger Games scene.

On last night's (May 24) Tonight Show, Lawrence joined host Jimmy Fallon and John Oliver for a game of True Confessions, in which they'd each have two envelopes: one hosted a truth and the other hosted a lie. After reading one, each contestant would be subject to a one-minute interrogation by the other two competitors, who would then guess whether the admission was real.

In the clip above, J. Law, who goes first, reads: "I once took an Ambien before filming a scene in The Hunger Games." Immediately, she cracks a smile, and the guys dig into her like a pair of gumshoes.

"Were you sleeping in the scene?" Fallon asks, but Lawrence shoots him down, insisting her character was actually dancing (KATNISS TURNT!!!).

"Was it a fight scene that you slept through?" Oliver poses.

"No, no. Do I just answer it yes or no?" the suspect denies.

When the 60 seconds are over, both guys guess that it's true — and Lawrence confirms she did, indeed, take a pill before Hunger Games cameras went up. Still, she insists it was a mistake.
